Thunderbolt: Black screen after closing MacBook
Since yesterday, my thunderbolt goes to black screen once I close my macbook. The screen works, because when my macbook is open and connected to Thunderbolt, it shows my screen picture on the Thunderbolt. Once closing my laptop to start working on the Thunderbolt, the screen goes black.
After restarting the whole, it is ok for a few seconds and then goes black again. What can it be?
Is this a good question?
